'Application filed October a, 1918. Serial No. 256,921.

i To all whom it may concern:

Be it known that I, JOSEPH H. GIEsKE, a citizen of the United States, residing at St. Paul, in the county of Ramsey and State of Minnesota, have invented a new and useful Improvement in Superpress Numbering-Machines, of which the following is a specification.

The primary object of this invention is the production of an automatic numbering subpress, which is particularly adapted for the manufacture of numbered tagssuch as are commonly employed-as license tags on vehicles and'for other purposes.

-More particularly the invention reduces any chanceof mistakes and accidents occurring in the' manufacture of numbered tags and relieves the operator of responsibility of changing number dies by hand. The invention also facilitates the eflicientproduction of numbered tags at less expense than heretofore and reduces the danger to a minimum of any harm occurring to operators in the manufacture of tags. The invention is equally applicable for use in manufacturing tags or plates having either raised or embossed surfacesorsunken impressions and whenmade out of any suitable material such as brass, aluminum, fiber, steel, iron, etc. Theinvention is particularlyalthough not necessarily adapted for use in a press of ordinary construction having a reciprocable movement or stroke of a ram, which for corn venience I have termed a super-press or power press. For further convenience I have termed my invention a sub-press for use in conjunction with said supenpress. The sub-press is adapted to receive its movement and compressing power from the superpress on which itis boltedor otherwise securedbetween compressing members and is 'adapted'to complete substantiallyfive operations in one, namely, numbering, embossing, shearing, punching and stripping.

Among furtherobjects' are simplicity of construction and greater effectiveness in use than heretofore. To these ends my invention comprises the features of construction and combination of parts hereinafter more particularly de scribed and claimed. In the acco mpanying drawings forming part of'this specification, Figure 1 is a side elevation of my invention, detail portions of'the compressing members of-a super-press being illustrated between which my invention is positioned and shown attached for use; Fig. 2 is a side elevation of one of the numbering slide dies arranged in one of the bolsters; Fig. 3 is a plan of the slide die illustrated in Fig. 2; Fig. 4 is a top plan of the lower bolster and its connected set of .numberingslide dies showing the pilot pins in sections and a vehicle tag in position thereon after it has been completed; Fig. 5 isa bottom plan of the upper bolster and its connected set of numbering slide dies showing the pilot pins in section and a vehicle tag in position after'it has been completed; Fig. 6 is a cross section taken substantially on the line X-Xof Fig. 4, and a corresponding line XX in Fig. 1; Fig. 7 is a section taken substantially on the line Y-Y of Fi 1 looking at the forward end of the bottom bolster; Fig. 8 is aside elevation of a detail of the bottom'bolsterand a portion of the lower set of numbering slide dies, a portion only of the bell crank operating lever being illustrated; Fig. 9 is a top plan view of the feed dog by which the numbering slide dies are stepped forwardly in the bolsters; Fig-10 is a side elevation of the feed dog, and Fig. 11 is a front end view of the feed dog.

For convenience in illustrating anddescribing my invention, I have shown detail portions of two reciprocable compressing members A and B of a super-press which may be of any usual constructionfthe members illustrated being adapted for'reciprocable movement either one or both being movable toward or away from eachother, the compressing action imparted thereby being adapted to operate my improved tag numbering die for cutting and forming tags B V out of sheet metal orother suitable material with raised or depressed numbers, figures or designs as desired.

'My invention includes in its mechanism a pair ofupper and lowerbolsters C and D. which are in the form of plates made of metal or out of any suitable material, which for convenience are provided with pairs of lugs 2 on their sides through which bolts such as 3 are fastened to secure the bolsters in proper position upon the compressing elements A and B. These bolsters are positionedone directly above the other with an intervening space in which the tan blanks from which the tags such as B may :thousands and ten thousands slides.

be placed in position to properly register with the dies. The lower and upper faces respectively of the upper and lower bolsters are formed with longitudinal passage ways or grooves t in which sets or clusters of numbering die slides E and E are assembled, the upper group E as illustrated =being five in number, arranged side by side to slide in the corresponding passage l and the lower set E being of corresponding number and arrangement, there being a units slide 5 a tens slide 6 a hundreds slide 7,

a thousands slide 8 and aten thousands slide 9in the upper group and a corresponding units slide 5, tens slide 6, hundreds slide'Z, thousands slide 8 and ten thousandsslide 9 in the lower group. The lower and upper faces respectively of the upper and lower units slides are arranged vertically one above the other, and this same arrangement follows, in connection with the pair of tens, hundreds, All of these die members are of substantially the same length. The lower faces of the upper group of slides and the upper faces of the lower group of slides are provided with numbering die plates of hard material running consecutively as follows: 1, 2, 3, l, 5, 6, 7, 8, 9, 0, from one end of the slide to the other, said die plates 10 being secured by dove tailing the die plate tightly into and across the face of the slide as illustrated. Each group of corresponding numeral die plates is arranged with its members situated side by side in alinement when the slides are normal, that is, all of the numerals 1 will be arranged in alinement transversely and all of the numerals 2 in the same manner, etc., there being a blank space left at the forward ends of the slides before the slides start on their operating career through the machine. The die plates referred to in each pair of corresponding upper andloi'ver slides are of male and female formation, so that in the compressing operation of the compressors A and B, the metal of each tag is either embossed or formed with depressed characters or designs. which the tag platesB are embossed and cut in the machine suitable guide, pins 11 are arranged, by which the tag blank may be properly positioned to be formed and cut. The bolster elements are also provided with cutting elements 12, which together with pins 11 are carried by die plates 13 which are dove-tailed and secured into the bolster elements and fastened by set screws 14. Suitable rim forming die elements 15 are also provided for forming the rim portion of the tag. These cutting and die elements are of usual character and merely cooperate in the cutting and stamping ofthe tag with my improved features of construction.

'lia hpair f uppe an le er numbering At the position in- .lower bolster.

that eacht methev compress slide die members is provided with a pair of pilot pins 16 and 17 disposed at the opposite ends of each pair, said pins being permanently secured to the lowermost slide, such as 5 and slidably secured to the corresponding upper slide, so that the pair of slides may close and are accurately guided together during the compression stroke of the compressing 'me'mber A of the superpress. These pilot pins cause each pair of numbering slide dies to move together longitudinally in the passage i of each bolster, so that when the slide dies close together their die plate members 10 will register ac curately. The numbering slde die menr' bersof the lower group are feathered together and in the corresponding bolster member by the feather orkey elements 18, this method of-slidably securing the number-- ing slide dies being employed in connection with both the lower and upper bolsters.

Each of the lower numberingslide die members is provided with a series of notches 19 across its lower surface, there being one ratchet tooth notch for each ordinal of the die members 10 in the surface of the slide. These notches correspond in all of the lower slides, that is the notches for all of the same ordinals are in alinement across the lower surfacesof the lower slides when all of the slides are in starting position. All of these ratchet notches are of equal depth, excepting the last ratchet notch 20 in each slide corresponding with the ten or naught ordinal. This notch is of greater depth for purposes to be hereinafter described. The lower portion of the lower bolster is formed with a longitudinal opening. 21, (see Fig! 7) in which is placed a, ratchet feed dog F which is in the form of five blockmembers 2-2 of substantially similar shape, excepting that their forward ends when the block members are arranged side by side in corresponding position have ratchet teeth Q3, 24,2, and 27 which increase in height successively. The block members 22 are mounted on a supporting bar 28, the middle block member being secured thereto by the set screw 29. The block members are also secured to a shaft 30, which is ']ournale d and slidably supported in slot 31 extending longitudinally through the'side portions 32 of the One end of the shaft 30, extends through a guide slot 33 (see Fig. 1) in r the arm 34 of a bell crank, the angleportion of which is pinioned by the pin 35 on one side of the lower bolster. The power arm 36 of the'bell crank is secured by the pin and slot connection 37 and 38 to an operating arm 39, which is pivotally secured by the pin 10 to the upper bolster member G. This bell crank and operating arm with 'connections are duplicated on both sides 2 of the bolsters. This mechanism is so arranged 'onmembers A ing position into reengaging position. Af-

ter reengaging the slide and during the raising or opening movement of the compressing elements of the super-press, the bell crank and operating arms 39 cause the ratchet dog to push the reengaged slide forwardly a step until a next succeeding die plate is moved into registering position to emboss a tag plate, which is next placed in position in the die with a succeeding number. As each numbering slide plate reaches embossing position with the number plates registering to emboss a tag plate, a depressible spring holder automatically engages the slide plate, which has been moved, and tends to hold it in registering position. Said holder comprises a ball 41 and a compression spring 42 both seated in a well or cavity 43 in the lower bolster there being one of the holders described placed below each slide. The depressible ball 41 is forced downwardly out of engagement with a slide during the thrust movement of each slide, but automatically reengages the slidein a cup or notch 44 in the lower surface ofthe slide below each number die, When the last die plate, namely the tens die, is about to be moved into operatingposition in the lower bolster, that is the position in which a pair of corresponding die members will form and cut a tag B in the machine, the highest shoulder member 27 on theratchet dog will enter the deep change number notch 20 in the slide, which has been previously moved and the next lower shoulder 26 on the ratchet dog will then engage the notches 19 and act upon the tens number slide die element and step. it forwardly anotch. Likewise the shoulder member 26 on the ratchet dog will enter a deep seated notch 20 in the tens slide at the end of its series of number dies and below the zero die. This same operation is repeated bytheratchet dog on all of the number die slides until the ten thousands slide hasbeenoperated. It will be noted that the depth of the notch 20 in all of the slides is equal or greater than the height of the highestshoulder 27 on the ratchet dog. The pair of unit number die slides is moved forward against tension to more positively cause the ratchet dog to reengage the slide in stepping it forward, said tension being produced by a weight 50 connected by a cable 51 traveling over sheaves 52 and secured to thelower slide by the eye bolt 53, and not sufficient to move the slide from being held by the bolster 41 automatically. It is not necessary to employ the tension mentioned to successfully operate my invention and the same can be dispensed with if desired and the slide returned by hand. A plunger pin 61 depressible under tension of spring 62 seated in the side of the bolster B has a' blade 63 which when the pin is depressed moves the bolster 41 out of engagement with the slide 5 thus relieving the slide and allowing it to be returned by the weight 50 into starting position and until the head of its pilot pin 17 strikes the end of the bolster D. The outer end of pin 61 projects from the side of bolster D convenient so that the operator can depress same by hand. The invention can also be provided when desired with an ejector 54 in the form of a plunger reciprocably disposed through the upper bolster C and the die plates 13, in positlon over the tag plate to free the tag plate from the upper die member after each embossing and cutting operation. This ejector 54 is urged downwardly a short distance below the face of the upper die member by a rocker arm 55 pivotally supported between its ends upon a stationary support 56 and situated with an operating arm 57 over a movable stop 58 carried by the compressing member A. A compression spring 59 serves to raise the ejector 54 with its lower surface above or even withthe surface of theupper die member when the compression member A descends. It is obvious that any'number of numbering die slidesmay be used according to the number of tags to be made. For instance if 10,000 tags are to be made the subpress constituting my improved change number die mechanism would have five double slides connected together by their pilot pins, or if 100,000 tags are to be made siX double slides will be employed. The numerals on the die slides are so positioned that the consecutive number to be embossed on the tag plate is' in the center of the die proper, and the bolster for embossing the edges of the tag will be centralized around the figures or numerals. In this position i as before stated, the depressible holding balls 41 enl l. i)

gage and tend to hold the slides in proper registering position and from further unintentional movement. If a tag of five nu meral's is to be made, the length and width which are connected to the topand bottom bolsters of the sub-press slides the ratchet dog member F back until one of its shoulders engages in the next succeeding notch 19 whereupon the slides so engaged during the succeeding upward stroke of the compresthe tag blank which is placed thereon in registering position with the pins 11. The plate which has been embossed by the compression movement oithe die members 1s knocked oil of the upperdie member by the ejector 5t when the ram or upper compression member reaches the upper end of its stroke. If the slide wh1ch has been stepped forwardly 1n the manner stated reaches a position with its ninth die couple in registering position for operation, the dog will then engage by its proper shoulder the next succeeding companion die slide due to the deep change number slot 20 being entered by the shoulder of the dog which has previously stepper a die slide ahead. The plunger 61 isthen depressed by hand to release the units slide back into starting position. This operation then repeats until another ninth movement is reached whereupon another change transpires. In this manner the engagement of the dog moves from one slide to another every ten, hundred, thousand and ten thousand change of the dog and compression members. If it is desired to repeat any number at any time, that is emboss a plurality of tag plates with the same number, the ratchet dog can be held from reengaging the slide which has previously been engaged by lifting the weight 41 by the handle member 60.
